Steps to be followed after importing the images to NBU.

In the following example, we have a database called SAMPLE. The recovery logs are included in the backup image, the database is restored, and then the database is rolled forward to the end of backup timestamp.

Step 1

Login to the NetBackup GUI navigate to Backup, Archive and Restore.

Step 2

Click on the Restore Files tab and select the Source, Destination Client and type of Policy to restore the DB2 backup files.

Step 3

Restore the image on the DB2 client as a file.

Note.png Note: Set Policy Type to standard, as the restore will be as flat files as opposed to DB2.

Step 4

Set a valid date range to look for the backup image. Make sure to change the Browse Directory to the "/" location, else the contents may not populate.

Step 5

Select the image to recover, and start the restore process back to a location on the client machine.

Step 6

Recovered filename will have a naming convention as shown below.

e.g. SAMPLE.0.DB2.NODE0000.CATN000.20180523164142.001

  • Database Name = Sample
  • Instance Name = DB2
  • Timestamp = 20180523164142
  • Catalog Name = CATN000

Step 7

Restore the database. The example below restores the database SAMPLE from location in "C:\Backup"

db2 => restore database sample from "C:\backup" taken at 20180919172832 with 2 buffers buffer 1024 parallelism 1 without prompting SQL2540W Restore is successful, however a warning "2539" was encountered during Database Restore while processing in No Interrupt mode.

Step 8

Roll the logs forward to the end of the backup to make sure the database is in a consistent state.

db2 => rollforward db sample to end of backup

Rollforward Status
Input database alias = sample
Number of nodes have returned status = 1
Node number = 0
Rollforward status = DB working
Next log file to be read = S0000000.LOG
Log files processed = -
Last committed transaction = 2018-09-19-16.28.42.000000 UTC

DB20000I The ROLLFORWARD command completed successfully.

Note : If log files are not included in backup images, the rollforward recovery needs to be done as per the method used for backing up logs.
